It is slightly if you have the rtp of 95% and say the cycle is however many spins you can do in 100 sessions.1 player doing 100 consecutive sessions from scratch will have somewhere near 95% rtp.If a hundred players play 1 session(1 after the other they will have a random rtp which is my point it's a complete lottery of who wins and loses irrespective of any stated rtp
You're assuming there's a fixed cycle of x number of spins. Which, as far as I'm aware, there isn't
The RTP is calculated from doing millions of test spins. The games aren't designed to hit their RTP over a FIXED number of spins.
The final absolutely exact RTP will only be known when the game is removed from service for the very last time. Because during play, the RTP is always going to fluctuate slightly.
